Having had my TV etc boxed up in the hall for the best part of a week, tomorrow I plan to set it all up. However I have a question regarding the placement of the centre speaker. Here's my ridiculously basic question. The Toshiba closed TV stand does not have enough space on its top shelf for me to sit my Quad L centre. The alternative would be to put it on the lower shelf which is just a few inches off the floor (with the door open when in use): or otherwise to put it on top of the TV. I've read different advice in various places. Would the lower shelf be too low? Cheers.
